Nowadays smartphones, tablets and desktop/laptop computers are all siblings. They use the same UI paradigms and follow the same idea of a programmable and flexible machine that's available to everyone. Only their hardware feature set and form factor differentiate them from each other. In this context, does it still make sense to consider them as separate devices as far as software development is concerned? Wouldn't it be a much better idea to consider them as multiple variations of the same concept, and release a unified software platform which spreads across all of them? This article aims at describing what has been done in this area already, and what's left to do.

Qt Quick is Qt Quick, Qt Stylesheets is Qt Stylesheets. One is largely inspired by CSS, the other is applications.

I.e., you have confounded those two technologies

As I said, I've yet to find a good introduction to the subject to clear up my vision of it. What I'm looking for is something written by a QT developer or enthusiast which explains in a few paragraphs, without going in technicalities...

* What's the point of those new QT technologies, what Nokia designed them for.
* Why I should use them as a developer, what they bring on the table, how they solve the problem which they were designed to solve.
